I am using the systeme
package to create an equation system.
I am also using the mtpro2
package for mathematical notation.
When I want to create a 2x2 system with a curly bracket it works just fine by using the command : \sysdelim\{.
.
But it seems that the curly bracket doesn't look the same in a 3x3 system or above.
\documentclass[b5paper,11pt]{article}
\usepackage{pgfplots}
\usepackage{psfrag}
\usepackage{amsmath}
\usepackage{mtpro2}
\usepackage{calc}
\usepackage{systeme}
\begin{document}
\sysdelim\{.\systeme{2x+3y=5,x-4y=-3\quad}
\sysdelim\{.\systeme[xzy]{2x+3y-z=5,x+2z-4y=-3,x+y=2}
\end{document}
How can i make the 2nd bracket look like the 1st?
EDIT 2020 - TeXLive issue after update 10/4/2020
I have just updated my TeXLive distribution to TexLive 2020 and tried to run the same code using the patch recommended by egreg at the second part of his answer. Apparently there is a new issue
LaTeX3 Error: '\msg_term:n' deprecated on 2020-01-01. Use '\iow_term:n '. {}{}
Where exactly must I replace that code?
\usepackage[straightbraces]{mtpro2}
should do.
